FUEL FOB INTERNAL-COMBUSTION ENGINES.

Io Drawing.

My invention relates to internal combustion engine practice, and it hasparticular relation to a novel fuelmixture which may be employedadvantageously therewith.

The principal and most satisfactory fuel which is now employed ininternal combustion engines, is ofhydrocarbon species. Its use isattended with certain shortcomings, however, which manifest themselvesby the overheating of the engine, premature detonations, or as iscommonly termed knock-= ing, carbon formation and other undesirableattributes. It is the object of this invention to overcome such defectsby mixing an ingredient with the fuel which will modify itscharacteristics in a manner whereby the recognized shortcomingsareobviated.

In practicing my invention, I dissolve from one hundredth of one percentto five percent, or any other desired proportion of an organic compound,such as aniline oleate in the fuel. The presence of this substanceevidences itself not only by its tendency to eliminate the carbonaceousresidue that normally deposits within the cylinder of the engine, but atthe same time aids in the lubrication, and otherwise improves theoperating characteristics of the motor. Thus,

' for example, the engine is not overheated readily, at the same time itruns more smoothly in that it does not display the usual knocking,characteristics that attend premature explosions within the cylinderchambers.

The present invention not only enables one to improve the operatingcharacteristics of the ordinary, gasoline engine by eliminating theknocking that is. often to be noted, but its use may be extended torelatively high compression combustion engines with the same advantages.corporating preferably from one tenth to three percent of theseingredients-$1 leaner mixture than is ordinarily possible can beemployed satisfactorily. It is evident therefore, that the-principlesunderlyin the invention are susceptible to many wi ely differentmodifications.

Obviously, other substances embodying aniline oleate may be utilized.Accordingly, in place of the oleate radical, other acid groups may besubstituted, particularly Furthermore, by inthe same general chemicalcharacteristics of Application filed October 18, 1926. Serial No.142,522.

those of the higher fatty acid series, such as stearic, palmitic andothers. Likewise, other amido bodies may be employed, particularly thoseof the aromatic series such as the toluidines, the xylidines andothers.-

In the same manner the various acid amides may be em loyed, andparticularly the anilides, tolui es and the xylides. Derivatives ofacidic bodies, and derivatives of basic bodies which are capable ofinteracting to form compounds having characteristics similar to anilineoleate for example, are considered to be within the sec of the termsacid and amine respectively, as herein employed.-

. It will be understood, of course, that while according to thepreferred embodiment, the salt or compound itself is dis-' solved orotherwise uniformly mixed with the hydrocarbon base, one may incorporatethe individual components preferable in equimolecular roportions withthe fuel, without departing from the spirit of the invention.Furthermore, the desired constituents may be added in other relativeproportions with or without diluents and coloring compositions.

While I have described a single specific embodiment of my invention, theprinciples underlying the same have been set forth in detail, and Idesire therefore, that the invention be limited only to accord with theprior art in the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. A fuel for internal combustion engines embodying a hydrocarbon baseand a material formed by the interaction of an organic acid and anamine.

2. A fuel for internal combustion engines embodying a hydrocarbon, anaromatic amine and an aliphatic acid.

3. A fuel for internal combustion engines embodying a hydrocarbon baseand aniline oleate. v

4. A fuel for internal combustion engines comprising a hydrocarbon base,an organic acid and an ammo body.

In testimony whereof, I aflix my signature.
